as；such ?as ?。as many/much as；so ?as等結(jié)構(gòu)中。如：※I have the same book as you(have).我有一本和你的一樣的書。Her attitude to him was quite the same as it had always been.(關(guān)系代詞as指示代詞same連用, 在從句中用作表語,

指時間，在定語從句中作時間狀語。其先行詞是表時間的名詞（如： time, day, week, tear, month, etc.）He came last night when I was will put off the piic until next week, when the weather would be ：先行詞為“時間名詞”，可用when引導(dǎo)定語從句，when在定語從句中作狀語；還可以用which或that 引導(dǎo)，which或that在從句中作主語或賓語。比較: I still remember the day when /on which my brother joined the army.（作狀語）Next month, when you will be in your hometown, is just around the still remember the days which/that we spent together.（作賓語）Next winter which/that you39。ll spend in Harbin, I39。m sure, will be shall never forget the day when Shen Zhou Ⅴ

I do such : Please do the experiment in the way（that/which）I have shown you.Ⅳ.限制性定語從句與非限制性定語從句的區(qū)別：，非限制性定語從句往往用逗號隔開。，限制性定語從句與先行詞關(guān)系緊密，起限定作用，如果去掉了這個定語從句，整個句子就不完整或者會改變意思；而非限制性定語從句與先行詞關(guān)系不是很緊密，對先行詞起補充說明或描述的作用。This is the book I like 。Beijing, which has been China39。s capital for more than 800 years , is rich in cultural and historic ，它有著豐富的文化和歷史遺產(chǎn)。，限制性定語從句可譯為一句（較短的一般譯為“的”字結(jié)構(gòu)）；而非限制性定語從句可譯為兩句。（見上句翻譯）比較:He has a sister, who is a has a sister
